The Pettypool Y DNA Project

If you are male, or a female with access to a male relative’s DNA, you can select a 37 marker Y DNA test at Family Tree DNA (FTDNA).  This test is relatively inexpensive but sufficiently precise to determine if you are likely to be positive for known Pettypool DNA Short Tandem Repeat (STR) patterns, or not.  You can find an explanation of STR tests at the FTDNA website Learning Center.  When you receive the results of your test, FTDNA will notify members of the Pettypool project that your result matches theirs, and one of the administrators will contact you with an invitation to join the Pettypool project.

The 37 marker STR test is an inexpensive basic test to verify potential Pettypool ancestry.  However, much more extensive tests are available that will more precisely place you in the Pettypool family tree.  The project administrators or other members can help you select any additional tests.  In addition, you will have access to other project members, with the possibility that you can learn more about your family or help other members with your knowledge.  There is a private discussion group on Facebook which has valuable discussion about Pettypool family DNA.  An administrator will issue you an invitation to join the Facebook group when you join the FTDNA project.

What if I Don’t have Male DNA?

The Pettypool Project was begun as a Y DNA project, and that is still the primary focus.  But we have members who are descended from female Pettypools, and some of them have Maternal Lineage mtDNA results to share.  You can find out more about this DNA test at the FTDNA’s website Learning Center.

And almost all members have also done a Family Finder test or have transferred the equivalent test from or other DNA test organization.  Working with other Project member’s FF results can advance your research without a Y chromosome test result.  You can find out more about Family Finder testing at FTDNA’s Learning Center.

The Paper Trail

The ultimate purpose of the Pettypool Project is to verify, correct, and expand the genealogy of the Pettypool family.  The most current record of the family’s history as derived from historical records is at the Pettypool Family One-Name Study website.  We are a member of the world-wide surname research organization the Guild of One-Name Studies as well.

The Big Picture- the Human Family Tree

If you have a Pettypool Y chromosome result, then you should consider joining these two DNA projects as well: R SRY2627/Z198/L176 and R DF27 and Subclades.  These projects are researching the ancient relationship of Pettypools with many other surname groups.

  1. I have no doubt I am a Pettypool. My father Aubrey E Blanks (1904-1993) was the son of Cynthia Ann P.Pool (1864-1953), daughter of William Benjamin P.Pool (1847-1928), son of Buckner P.Pool (Pettypool)(1800-1875) moved to KY along with his father Seth Pettypool (1774-1834) and step-mother Elizabeth Wilson. Buckner’s mother was Nancy Pettypool. She was the daughter of Benjamin Pettypool and Rodah Overby.

    Seth’s father was William III. son of Seth, son of William II son of William Sr who was born in England I believe, There is an arrival from England to Maryland 1665. This where I question as I have no proof that this is my William.

  2. Thank you for your comment. I do agree that your lineage as listed is Pettypool. The Pettypool DNA Project is attempting to use the new Y700 SNP test at FTDNA to create a “DNA tree” that we can map to the genealogical “paper trail”. Doing so will assist those who are “brick-walled” and provide additional confirmation to those with paper trails. And of course there is always the possibility that DNA testing will uncover branches of the family as yet undiscovered in traditional genealogy.

    To do this, we need input from as broad a sample as possible. Currently we don’t have as much participation from the William(3) lineage as from the Seth(3) line. If you know of a male descendant from your William line that would be interested in participating in the project, we would welcome his joining the project.
